DISTRIBUTOR BRUSH HOLDER IN MAGNETO IGNITION APPARATUS FOR INTERNAL- COMBUSTION ENGINES.

Specification of Letters Patent.

Application filed May 14, 1920. Serial No. 381,524.

To all whom it may concern:

Be it known that I, Go'r'rmnn STEINER, a citizen of the Swiss Republic, residing at ()bach 304, Solothurn, Switzerland. have invented certain new and useful Improvements in the Distributor Brush Holders in Magneto Ignition Apparatus for Internal- (ombustion Engines, of which the following is a specification.

It is well known in magneto-ignition apparatus for internal combustion engines that the parts composed of insulating material, are very liable to break notwithstanding the most careful construction. Furthermore such ignition apparatus, more particularly those intended for use with motor cycles or small internal combustion motors, are in many cases subjected to rough treatment.

According to this invention the removable double ln'ush-holders composed of insulating material used in the igniting apparatus of internal combustion engines are arranged in a sunken position between two flanges so that they are comparatively well protected against shocks and blows, whilst yet being readily accessible and capable of being easily removed from the side. A smooth outer contour for the distributor is thus obtained and no bare current carrying parts appear on the outer surface.

The improved arrangement is illustrated in the accompanying drawings in Fig. l in side elevation, and in Fig. 2 in plan and partly in horizontal section.

The two brush-holders a Whose brushes I) rub on the distributing roller 0, are in this case situated in the front bearing end plate (I of the igniting apparatus 6, and they are arranged between the flanges f and g of the latter so that the brush-holders a are readily accessible from outside and can be easily removed by turning them outwardly and laterally, and yet are Well sheltered.

What I claim is 1. In a magneto-ignition apparatus for internal combustion engines, the combination with the casing of the magneto-ignition apparatus, of a pair of laterally extending flanges formed on one side of said casing, a corresponding pair of flanges formed on the opposite side of said casing, and a laterally removably distributor brush holder mounted in a sunken position between each said pair of flanges.

2. In a magneto-ignition apparatus for internal combustion engines, the combination with the casing of the magneto-ignition apparatus, of a pair of laterally extending flanges formed on one side of the front bearing end plate of said casing, a corresponding pair of flanges formed on theopposite side of said front bearing end plate of said casing, and a laterally removable distributor brush holder mounted in a sunken position between each said pair of flanges.

In testimony whereof I have signed my name to this specification.
